Your boat can certainly be built outside. Many others have done it. But if you can do it, you really should build your boat in some kind of protective structure. Trust me. When the wind picks up, you'll have problems with blowing dirt in your epoxy, leaves will pile up under the boat and all around your power tools. When you right the hull, rainwater will collect and soak the wood before you get a chance to protect it and it goes on and on. Go to this URL and check out the plans for the Stimson Marine bowroof. It's fast, simple and looks like it does a great job providing the shelter your project will need.

I will look afther this idea more (I have alredy been there), and see.
I think this was quite a good idea, the best I know to day. And the price was just what I have in my mind. Have looked at many uppertunities, but they where too expensives.
